LPIS secretary Matthew Doyle accused Tory Brexiteers of being "willing to throw the Good Friday Agreement under the bus and risk the return of a border on the island of Ireland".

"This is totally unacceptable. It's right that we as the Labour Party Irish Society take the lead by speaking out now to say that there is no better deal that the one we have now with Britain and Ireland together in the European Union," he said.

"The politicians are deadlocked. It's time to give the public a final say in a referendum so that we can protect the peace and prosperity that Britain and Ireland have enjoyed since the Good Friday Agreement and keep the benefits of our European Union membership."
